At this stage, it is necessary to decide on concepts such as the resolution of the picture, the frequency of personnel and the bitrate video and audio flow. Everything is simple with resolution — what is the format of the display screen at the mobile phone, this should be the permission of the video file. If the standard of your phone is 320 on 240, then the video flow is 320×240. Otherwise, the image will turn out to be too compressed or stretched. The “High -Show Frequency” indicator depends on the characteristics of the “iron”. The higher the frequency of personnel, the more resources for video processing are required. We suggest you use the already voiced advice. See what frequency of personnel has the video that is shown on the screen of the mobile phone without freezing and fragmentation of the image. In addition, the frame rate can be selected experimentally. The Bitrate Council Council is similar — either an experiment with different values, or the value that is declared in the video with the best quality.
